Abstract
In order to analyse the relationship of the change of PM2.5 with each meteorological factor, the PM2.5 was collected in eight monitoring sites of Xi'an, and the data of meteorological factors was provided by NOAA. The paper analyses daily changing trend of PM2.5, and studies its relevancy with air visibility, air speed, temperature and relative humidity. Results show that PM2.5 density has negative correlation with air visibility and speed, good positive correlation with temperature, and when relative humidity is lower than 60%, the relation is positive, while relative humidity is within the range of 61%~100%, the relation is strongly negative. The article provides a reference for fine particulate matter control and its prevention in Xi'an.
